A Model for Empowering Rural Solutions for Cervical Cancer Prevention (He Tapu Te Whare Tangata): Protocol for a Cluster Randomized Crossover Trial

BACKGROUND

Māori are the Indigenous people of Aotearoa (New Zealand). Despite global acceptance that cervical cancer is almost entirely preventable through vaccination and screening, wāhine Māori (Māori women) are more likely to have cervical cancer and 2.5 times more likely to die from it than non-Māori women. Rural Māori residents diagnosed with cervical cancer have worse outcomes than urban residents. Living in rural Aotearoa means experiencing barriers to appropriate and timely health care, resulting from distance, the lack of community resourcing, and low prioritization of rural needs by the health system and government. These barriers are compounded by the current screening processes and referral pathways that create delays at each step. Screening for high-risk human papillomavirus (hrHPV) and point-of-care (POC) testing are scientific advances used globally to prevent cervical cancer.

OBJECTIVE

This study aims to compare acceptability, feasibility, timeliness, referral to, and attendance for colposcopy following hrHPV detection between a community-controlled pathway and standard care.

METHODS

This is a cluster randomized crossover trial, with 2 primary care practices (study sites) as clusters. Each site was randomized to implement either pathway 1 or 2, with crossover occurring at 15 months. Pathway 1 (community-controlled pathway) comprises HPV self-testing, 1-hour POC results, face-to-face information, support, and immediate referral to colposcopy for women with a positive test result. Pathway 2 (standard care) comprises HPV self-testing, laboratory analysis, usual results giving, information, support, and standard referral pathways for women with a positive test result. The primary outcome is the proportion of women with hrHPV-positive results having a colposcopy within 20 working days of the HPV test (national performance indicator). Qualitative research will analyze successes and challenges of both pathways from the perspectives of governance groups, clinical staff, women, and their family. This information will directly inform the new National Cervical Screening Program.

RESULTS

In the first 15-month period, 743 eligible HPV self-tests were performed: 370 in pathway 1 with POC testing and 373 in pathway 2 with laboratory testing. The positivity rate for hrHPV was 7.3% (54/743). Data collection for the second period, qualitative interviews, and analyses are ongoing.

CONCLUSIONS

This Māori-centered study combines quantitative and qualitative research to compare 2 clinical pathways from detection of hrHPV to colposcopy. This protocol draws on rural community practices strengths, successfully engaging Māori from a whānau ora (family wellness) approach including kanohi ki te kanohi (face-to-face), kaiāwhina (nonclinical community health workers), and multiple venues for interventions. It will inform the theory and practice of rural models of the use of innovative technology, addressing Māori cervical cancer inequities and facilitating Māori wellness. The findings are anticipated to be applicable to other Indigenous and rural people in high-income countries.

Culturally Safe Neonatal Care: Talking With Health Practitioners Identified as Champions by Indigenous Families

The burden of health inequities borne by Indigenous peoples can be overwhelming, especially when mothers and newborns' lives are at stake and health services seem slow to invest in responsiveness. In Aotearoa (New Zealand), urgent action is required to eliminate persistent systemic inequities for Māori (Indigenous) whānau (family collectives that extend beyond the household). This Kaupapa Māori (by Māori, for Māori) qualitative study aimed to explore the views of health practitioners identified as champions by whānau of preterm Māori infants. Ten health practitioners were interviewed and asked about their involvement with the whānau, their role in explanations and communication, and their thoughts on whānau coping. Interview data were analysed using interpretative phenomenological analysis. Three superordinate themes were identified: working together in partnership, a problem shared is a problem halved, and sacred space. Collaboration between health practitioners and with whānau was important to the champions and central to their goal of enabling whānau autonomy. This was built on a foundation of connectivity, relationships, and a full appreciation that childbirth is a sacred time that is potentially disrupted when an infant is born prematurely. The values- and relationship-based practices of these champions protected and uplifted whānau. They showed that health practitioners have important roles in both the elimination of inequities and the sustaining of Māori self-determination. This championship is an exemplar of what culturally safe care looks like in day-to-day practice with Māori and is a standard that other health practitioners should be held to.

Infant Sleep Hazards and the Risk of Sudden Unexpected Death in Infancy

OBJECTIVE

To examine the effects of infant sofa-sleeping, recent use by caregivers of alcohol, cannabis, and/or other drugs, and bed type and pillows, on the risk of sudden unexpected death in infancy (SUDI) in New Zealand.

STUDY DESIGN

A nationwide prospective case-control study was implemented between March 2012 and February 2015. Data were collected during interviews with parents/caregivers. "Hazards" were defined as infant exposure to 1 or more of sofa-sleeping and recent use by caregivers of alcohol, cannabis, and other drugs. The interaction of hazards with tobacco smoking in pregnancy and bed sharing, including for very young infants, and the difference in risk for Māori and non-Māori infants, also were assessed.

RESULTS

The study enrolled 132 cases and 258 controls. SUDI risk increased with infant sofa-sleeping (imputed aOR [IaOR] 24.22, 95% CI 1.65-356.40) and with hazards (IaOR 3.35, 95% CI 1.40-8.01). The SUDI risk from the combination of tobacco smoking in pregnancy and bed sharing (IaOR 29.0, 95% CI 10.10-83.33) increased with the addition of 1 or more hazards (IaOR 148.24, 95% CI 15.72-1398), and infants younger than 3 months appeared to be at greater risk (IaOR 450.61, 95% CI 26.84-7593.14).

CONCLUSIONS

Tobacco smoking in pregnancy and bed sharing remain the greatest SUDI risks for infants and risk increases further in the presence of sofa-sleeping or recent caregiver use of alcohol and/or cannabis and other drugs. Continued implementation of effective, appropriate programs for smoking cessation, safe sleep, and supplying safe sleep beds is required to reduce New Zealand SUDI rates and SUDI disparity among Māori.

He Tamariki Kokoti Tau: Families of Indigenous Infants Talk about Their Experiences of Preterm Birth and Neonatal Intensive Care

Māori (Indigenous peoples of Aotearoa New Zealand) bear an unequal burden of poor perinatal health outcomes, including preterm birth. An infant arriving preterm disrupts the birth imaginary of whānau (family collectives) and situates them in a foreign health environment that may not be culturally safe and nurturing. A cross-sectional interpretative phenomenological analysis of first interviews with 19 whānau participating in a Kaupapa Māori (by, with, for Māori) qualitative longitudinal study of preterm birth identified themes from their experiences and the meanings they attributed to them. Preterm birth was an emotional roller coaster, with the birth imaginary and anticipated roles disrupted as health practitioners took over the care of their infants. Whānau expressed the desire to be close to their infants, holding them, loving them, nurturing them, and emplacing them within whakapapa (genealogy, continual layering of foundations) networks. When health practitioners or hospital policies inhibited this intimacy by isolating, excluding, or discriminating, whānau were frustrated. Being familiar with hospital routines, staff, peers, infant cares, and being wrapped in wider whānau support were key for whānau coping. Whakawhanaungatanga (processes of establishing relationships) create safe spaces for whānau to be themselves. This quietens the 'storm' and returns whānau to a sense of calm, through the reclamation of their environment.

Pēpē-infant sleep practices and sudden unexpected death in infancy in Aotearoa New Zealand

OBJECTIVE

To explore pēpē [infant] sleep practices and the key motivators among selected Māori and non-Māori māmā [mothers] in Auckland, New Zealand, in relation to the risk of sudden unexpected death in infancy (SUDI).

METHODS

Qualitative research underpinned by a kaupapa Māori cultural framework was undertaken. In-depth face-to-face interviews occurred in the homes of māmā with young pēpē born in Counties Manukau, Auckland. Interview transcripts were analyzed using general purpose thematic analysis.

RESULTS

Thirty māmā participated, including 17 Māori. Two-thirds of māmā reported previous or current bed sharing. The fundamental human need for adequate sleep motivated half the māmā in the present study, and especially Māori māmā, to bed share. The second most common reason given was closeness and convenience. This was followed by breastfeeding, which was cited as a reason by Māori māmā only. These findings were interpreted in terms of intrinsic fear, culture, and māmā deployment of knowledge.

CONCLUSION

Service providers are encouraged to respond to the lived experiences and cultural realities, values, and beliefs of māmā when designing and delivering effective SUDI prevention interventions. Innovative approaches for providing structured and opportunistic, culturally appropriate education and support around safe sleep are likely to be well-received by māmā and their whānau [family/ies].

He Tapu Te Whare Tangata (sacred house of humanity): Under-screened Māori women talk about HPV self-testing cervical screening clinical pathways

OBJECTIVE

To develop an in-depth understanding of HPV self-testing cervical screening clinical pathways for never-/under-screened Māori women.

METHODS

Based on a community-based cluster randomized controlled trial in Aotearoa (New Zealand), a Kaupapa Māori (by Māori, for Māori) qualitative study enrolled Māori women who met the eligibility criteria of the HPV trial intervention (aged 25-69 years, no screen in >4 years). In total, 28 were recruited (22 had a negative test, six had a positive test and colposcopy). They were asked about their clinical pathway.

RESULTS

The HPV self-test was seen as empowering and promoting bodily autonomy, although some women expressed fears or misconceptions about this new technology. While those with a negative test were relieved, for the six women who had a positive test, there were many fears, compounded by seeking out information on the Internet. When attending colposcopy, the importance of support and responsive care was emphasized.

CONCLUSION

HPV self-testing has the potential to improve access to cervical screening and reduce inequities for Māori. Care must be taken in the delivery of screening and colposcopy results. Primary care and colposcopy services need to take special care with never-/under-screened Māori women to provide sensitive, responsive care, and mitigate trauma.

He Tamariki Kokoti Tau: Tackling preterm incidence and outcomes of preterm births by ethnicity in Aotearoa New Zealand 2010-2014

OBJECTIVE

To explore preterm birth among Māori indigenous peoples through Kaupapa Māori research of preterm birth in Aotearoa New Zealand.

METHODS

Linked maternity, mortality, and hospital data were analyzed for women and their infants born between January 1, 2010 and December 31, 2014. Relative risks (RR) were calculated for each ethnic group for preterm birth, small for gestational age (SGA), and mortality.

RESULTS

Adjusted rates showed that compared with Māori women, European women were at significantly less risk of having extremely and very preterm infants (RR 0.86, 95% confidence interval [CI] 0.76-0.95). Preterm infants of European women had a significantly lower adjusted RR of early neonatal death (RR 0.65, 95% CI 0.45-0.93) or post-neonatal death (RR 0.41, 95% CI 0.26-0.64). In addition to ethnicity, preterm rates were influenced by maternal age, body mass index, smoking status, and SGA status.

CONCLUSION

This study demonstrates that the Aotearoa New Zealand maternity system privileges whiteness, suggesting that clinical pathways for evidence-based medical care are not delivered systemically and equitably for all. Health pathways that focus on equity as a fundamental right will enhance health outcomes for Māori women and their infants.

Examining the potential preventability of adverse fetal/neonatal outcomes associated with severe maternal morbidity

BACKGROUND

Severe maternal morbidity (SMM) occurs in 1-2% of pregnancies. Despite the knowledge that a SMM event can contribute to poor fetal/neonatal outcomes, little is known about the preventability of these adverse outcomes.

AIMS

To examine adverse fetal/neonatal outcomes associated with SMM to determine if these outcomes were potentially preventable.

MATERIALS AND METHODS

A New Zealand national retrospective cohort study examining cases of SMM with an adverse fetal/neonatal outcome. Maternity and initial neonatal care were explored by multidisciplinary panels utilising a preventability tool to assess whether the fetal/neonatal harm was potentially preventable. Adverse fetal/neonatal outcomes were defined as fetal or early neonatal death, Apgar score <7 at five minutes, admission to neonatal intensive care unit or special care baby unit and neonatal encephalopathy.

RESULTS

Of 85 cases reviewed, adverse fetal/neonatal outcome was deemed potentially preventable in 55.3% of cases (n = 47/85). Preventability was related to maternal antenatal/peripartum care (in utero) in 39% (n = 33/85), to initial neonatal care (ex utero) in 36% (n = 29/80), and to both maternal and neonatal care in 20% (16/80) of cases. Main contributors to potential preventability were factors related to healthcare providers, particularly lack of recognition of high risk, delayed or failure to diagnose, and delayed or inappropriate treatment.

CONCLUSIONS

Multidisciplinary panels found that over half of adverse fetal/neonatal harm associated with SMM was potentially preventable. The novel approach of examining both maternal and neonatal care identifies opportunities to improve fetal/neonatal outcomes associated with SMM at multiple points on the perinatal continuum of care.

An Affront to Her Mana: Young Māori Mothers' Experiences of Intimate Partner Violence

Young Māori mothers in Aotearoa/New Zealand are disproportionately vulnerable to intimate partner violence (IPV) due to multiple intersecting factors, such as relationship dynamics during youth, pregnancy, and racialized Māori (Indigenous) identity. An enduring legacy of settler colonialism has resulted in Māori being overrepresented as victims and perpetrators of violence. IPV, in particular, leads to adverse social, mental, and health outcomes over time, including those specific to mothers (e.g., postpartum depression, miscarriage). This study analyzed six narrative interviews with young Māori mothers aged 14 to 19 from the E Hine longitudinal maternal health care study. Kaupapa Māori (by Māori, for Māori) was the primary research framework, which allowed for the use of Māori modes of engagement and the centering of Māori women's voices in the research process. Using a thematic and interpretive phenomenological analysis (IPA), we aimed to understand the lived realities of young Māori mothers who have experienced IPV and to examine the extent to which service responsiveness has been culturally safe. Our findings illustrated how IPV manifests in the relationships of these six women. Their stories showed the various ways in which young Māori women resist violence, reclaim their Māori identities, and experience personal transformation during their motherhood journeys despite abuse. We find that whānau (extended family) is both a violence-perpetuating and immensely protective factor. Moreover, there are structural and institutional barriers to culturally safe service responsiveness for young Māori women. These come in the form of racism at the frontlines of government agencies, pervasive victim-blaming, and a lack of earnest decolonial structural change at the institutional level. We conclude that social services must be multisectoral, culturally safe, and specialized for Māori youth and families to support Māori mothers experiencing IPV.

A call for action that cannot go to voicemail: Research activism to urgently improve Indigenous perinatal health and wellbeing

In this call to action, a coalition of Indigenous and non-Indigenous researchers from Australia, Aotearoa New Zealand, United States and Canada argue for the urgent need for adequately funded Indigenous-led solutions to perinatal health inequities for Indigenous families in well-resourced settler-colonial countries. Authors describe examples of successful community-driven programs making a difference and call on all peoples to support and resource Indigenous-led perinatal health services by providing practical actions for individuals and different groups.

Achieving cervical cancer elimination among Indigenous women

Achieving the World Health Organisation (WHO) cervical cancer elimination target of fewer than four new cases per 100,000 woman-years requires scaling up HPV vaccination of girls, cervical screening, and pre-cancer and cancer treatment. We reviewed data from four high-income colonised countries (Australia, Canada, Aotearoa New Zealand (NZ), and the United States (US)) to identify how each is currently performing compared to the cervical cancer incidence elimination and triple-intervention targets, nationally and in Indigenous women. We also summarise barriers and enablers to meeting targets for Indigenous women. To achieve elimination, cervical cancer incidence must be reduced by 74% in Indigenous women in Australia, and 63% in Maori women in NZ; data were not published in sufficient detail to compare incidence in Indigenous women in Canada or the US to the WHO target. Only Australia meets the vaccination coverage target, but uptake appears comparatively equitable within Australia, NZ and the US, whereas there appears to be a substantial gap in Canada. Screening coverage is lower for Indigenous women in all four countries though the differential varies by country. Currently, only Australia universally offers HPV-based screening. Data on pre-cancer and cancer treatment were limited in all countries. Large inequities in cervical cancer currently exist for Indigenous peoples in Australia, Canada, New Zealand and the US, and elimination is not on track for all women in these countries. Current data gaps hinder improvements. These countries must urgently address their systemic failure to care and provide health care for Indigenous women.

He Korowai Manaaki (Pregnancy Wraparound Care): Protocol for a Cluster Randomized Clinical Trial

Background

Maternal and infant health inequities between Māori (the Indigenous peoples of Aotearoa New Zealand) and New Zealand European women are well documented and cannot be explained solely by socioeconomic status. A research center-iwi (tribal group) partnership aims to address these disparities and improve maternal and infant health outcomes by implementing an augmented maternity care pathway (He Korowai Manaaki) to improve access to services and evidence-informed care.

Objective

The objective of this study is to test whether an augmented maternity care pathway improves Māori infant health outcomes.

Methods

This is a Kaupapa Māori (by, with, and for Māori) cluster randomized clinical trial involving 8 primary care practices allocated to either an intervention arm or control arm. The intervention arm comprises an augmented maternity care pathway (He Korowai Manaaki) offering clinical care through additional paid health care appointments and improved access to social support (eg, housing, transport). The control arm is usual care. The primary outcome is increased timely vaccination for Māori infants, defined as all age-appropriate vaccinations completed by 6 months of age.

Results

Recruitment commenced in November 2018 and was completed in June 2020, with 251 enrolled women recruited in intervention primary care practices before 20 weeks of pregnancy. Publication of results is anticipated in late 2023.

Conclusions

The results will inform primary health care policy including whether the provision of augmented maternal care pathways reduces disparities in the structural determinants of health. If effective, He Korowai Manaaki will strengthen the health and well-being of pregnant Māori women and their babies and improve their health outcomes, laying a strong foundation for lifelong health and well-being.

Te Hā o Whānau: A culturally responsive framework of maternity care

AIM

A nuanced healthcare framework, Te Hā o Whānau, aims to make the maternal-infant healthcare system more accessible and culturally responsive for Māori following unexpected events that led to the harm or loss of their baby.

METHOD

Te Hā o Whānau was developed from three components. Firstly, it was grounded and informed by Kaupapa Māori qualitative research involving whānau who had experienced the harm or loss of their baby. These learnings were then combined with mātauranga Māori (Māori knowledge) and built on three articles of Te Tiriti o Waitangi: Kāwanatanga, Rangatiratanga and Ōritetanga.

RESULTS

Te Hā o Whānau has been developed to specifically guide the maternal-infant healthcare system in providing culturally responsive practice points and guidelines. These practice points and guidelines align with three tikanga Māori (customs): Tikanga manaakitanga, Tikanga rangatiratanga and Tikanga whakawhanaunga.

CONCLUSION

To address the stark health inequities present, we must forge innovative models and strategies, rather than reproducing (less successful) paths that have the less resistance. Te Hā o Whānau is provided with the aim of providing better outcomes for all, not just Māori.

Examining adverse fetal/neonatal outcomes associated with severe maternal morbidity

BACKGROUND

While there is a global focus on severe maternal morbidity (SMM), less is known about the impact of SMM on fetal and neonatal outcomes.

AIMS

To examine fetal/neonatal outcomes associated with SMM.

MATERIALS AND METHODS

A national New Zealand (NZ) retrospective cohort study describing fetal/neonatal outcomes of all women with SMM admitted to a NZ Intensive Care Unit (ICU) or High Dependency Unit (HDU) in 2014. Adverse fetal/neonatal outcomes were defined as one or more of the following: fetal or early neonatal death, hypoxic ischaemic encephalopathy, Apgar score less than seven at five minutes, admission to Neonatal Intensive Care Unit or Special Care Baby Unit.

RESULTS

There were 400 women with SMM admitted to NZ ICU/HDU units in 2014, and 395 (98.8%) had complete birth/pregnancy outcome information. Of these, 49.4% (195/395) were associated with an adverse fetal/neonatal outcome. Indigenous Māori women had a 30% higher rate of adverse fetal/neonatal outcome compared to NZ European women (63.7% and 48.9% respectively; relative risk = 1.30, 95% CI 1.04-1.64). Pre-eclampsia was associated with an adverse fetal/neonatal outcome in 67% (81/120). Perinatal-related mortality rate was 53.1 per 1000 total births compared to NZ perinatal mortality of 11.2 per 1000 total births for 2014.

CONCLUSION

SMM events are associated with high rates of adverse fetal/neonatal outcomes with a higher burden of adverse events for Māori. Further research is needed to explore opportunities in maternal and neonatal care pathways to improve fetal/neonatal outcomes and address inequities.

New screen on the block: non-invasive prenatal testing for fetal chromosomal abnormalities

Non-invasive prenatal testing (NIPT) is a new screen for fetal chromosomal abnormalities. It is a screening test based on technology that involves the analysis of feto-placental DNA that is present in maternal blood. This DNA is then analysed for abnormalities of specific chromosomes (eg 13, 18, 21, X, Y). NIPT has a much higher screening capability for chromosomal abnormalities than current combined first trimester screening, with ~99% sensitivity for trisomy 21 (Down syndrome) and at least a 10-fold higher positive predictive value. The low false-positive rate (1-3%) is one of the most advertised advantages of NIPT. In practice, this could lead to a significant reduction in the number of false-positive tests and the need for invasive diagnostic procedures. NIPT is now suitable for singleton and twin pregnancies and can be performed from ~10 weeks in a pregnancy. NIPT is not currently publicly funded in most countries. However, the increasing availability of NIPT commercially will likely lead to an increase in demand for this as a screening option. Given the high numbers of women who visit a general practitioner (GP) in their first trimester, GPs are well-placed to also offer NIPT as a screening option. A GP's role in facilitating access to this service will likely be crucial in ensuring equity in access to this technology, and it is important to ensure that they are well supported to do so.

Acceptability of self-taken vaginal HPV sample for cervical screening among an under-screened Indigenous population

BACKGROUND

Human papillomavirus (HPV), the causative agent of cervical cancer, can be screened for using self-collected vaginal samples (self-testing). This may overcome barriers to screening for Māori women who suffer a greater burden of cervical disease than New Zealand European women.

AIMS

This study aimed to explore the potential acceptability of HPV self-testing for never/under-screened (self-reported no cervical screen in 4+ years, aged 25+) Māori women by Kaupapa Māori (by, with and for Māori) mixed methods, involving hui (focus groups/interviews) and survey.

MATERIALS AND METHODS

Community-based researchers ran hui with women in four regions (N = 106) and supported hui participants to collect survey data (N = 397). Healthcare providers (HCPs) were also interviewed (N = 17). Hui data were thematically analysed. Survey data were analysed by age group, rural/urban, primary health organisation (PHO) enrolment, and time since last cervical screen.

RESULTS

Most survey participants were PHO-enrolled (87.15%) and attended regularly (71.79%), but did not attend regular cervical screening. A desire for bodily autonomy, including whakamā (embarrassment/shyness/reticence), was the most frequently cited barrier. Three in four women reported being likely/very likely to do an HPV self-test. Nine in ten women reported being likely/very likely to attend follow up if they receive a positive HPV test result. Women and HCPs in the hui emphasised the importance of health literacy, cultural competence and empathetic support.

CONCLUSION

The findings indicate that with a culturally competent introduction of HPV self-testing, many currently never/under-screened Māori women would be willing to be screened and followed up if necessary. HPV self-testing has the potential to save lives.

He Korowai Manaaki: mapping assets to inform a strengths-based, Indigenous-led wrap-around maternity pathway

A research partnership between Iwi (tribal group) Ngāti Pāhauwera and a university-based research centre specialising in Kaupapa Māori (by Māori, for Māori) research was formed in response to an invitation from Ngāti Pāhauwera. The initial partnership goal was to address health inequities experienced by Māori women and infants in Te Wairoa (the home place of the Iwi), a predominantly Māori, rural region in Aotearoa (New Zealand). The research developed by the partnership is an example of a culturally responsive research methodology. Key features include: being Iwi-initiated; community identification of strengths and assets; guidance by a community steering group; contribution to local Māori research capacity; and the development of a community-led augmented maternity care pathway that is now being delivered through primary care. These features have strengthened the engagement of the Iwi, researchers and community, and provided opportunities for transformative change.

Smoking in pregnancy is a key factor for sudden infant death among Māori

AIM

To examine the sudden unexpected death in infancy (SUDI) disparity between Māori and non-Māori in New Zealand.

METHODS

A nationwide prospective case-control study ran from March 2012 to February 2015. Exposure to established SUDI risk factors was analysed to investigate the disparity experienced by Māori. Infant ethnicity was based on mother's ethnicity. Māori ethnicity was prioritised. Non-Māori includes Pacific, Asian, NZ European and Other.

RESULTS

There were 137 cases and 649 controls. The Māori SUDI rate was 1.41/1000 live births compared to 0.53/1000 for non-Māori. Parents/caregivers of 132 cases (96%) and 258 controls (40%) were interviewed. Smoking in pregnancy was associated with an equally increased SUDI risk for Māori (adjusted OR = 8.11, 95% CI = 2.64, 24.93) and non-Māori (aOR = 5.09, 95% CI = 1.79, 14.47), as was bed-sharing (aOR = 3.66, 95% CI = 1.49, 9.00 vs aOR = 11.20, 95% CI = 3.46, 36.29). Bed-sharing prevalence was similar; however, more Māori controls smoked during pregnancy (46.7%) than non-Māori (22.8%). The main contributor relating to increased SUDI risk for Māori/non-Māori infants is the combination of smoking in pregnancy and bed sharing.

CONCLUSION

The association between known SUDI risk factors, including bed sharing and/or smoking in pregnancy and SUDI risk, is the same regardless of ethnicity. Māori infants are exposed more frequently to both behaviours because of the higher Māori smoking rate.

A global view of severe maternal morbidity: moving beyond maternal mortality

BACKGROUND

Maternal mortality continues to be of great public health importance, however for each woman who dies as the direct or indirect result of pregnancy, many more women experience life-threatening complications. The global burden of severe maternal morbidity (SMM) is not known, but the World Bank estimates that it is increasing over time. Consistent with rates of maternal mortality, SMM rates are higher in low- and middle-income countries (LMICs) than in high-income countries (HICs).

SEVERE MATERNAL MORBIDITY IN HIGH-INCOME COUNTRIES

Since the WHO recommended that HICs with low maternal mortality ratios begin to examine SMM to identify systems failures and intervention priorities, researchers in many HICs have turned their attention to SMM. Where surveillance has been conducted, the most common etiologies of SMM have been major obstetric hemorrhage and hypertensive disorders. Of the countries that have conducted SMM reviews, the most common preventable factors were provider-related, specifically failure to identify "high risk" status, delays in diagnosis, and delays in treatment.

SEVERE MATERNAL MORBIDITY IN LOW AND MIDDLE INCOME COUNTRIES

The highest burden of SMM is in Sub-Saharan Africa, where estimates of SMM are as high as 198 per 1000 live births. Hemorrhage and hypertensive disorders are the leading conditions contributing to SMM across all regions. Case reviews are rare, but have revealed patterns of substandard maternal health care and suboptimal use of evidence-based strategies to prevent and treat morbidity.

EFFECTS OF SMM ON DELIVERY OUTCOMES AND INFANTS

Severe maternal morbidity not only puts the woman's life at risk, her fetus/neonate may suffer consequences of morbidity and mortality as well. Adverse delivery outcomes occur at a higher frequency among women with SMM. Reducing preventable severe maternal morbidity not only reduces the potential for maternal mortality but also improves the health and well-being of the newborn.

CONCLUSION

Increasing global maternal morbidity is a failure to achieve broad public health goals of improved women's and infants' health. It is incumbent upon all countries to implement surveillance initiatives to understand the burden of severe morbidity and to implement review processes for assessing potential preventability.

He Tamariki Kokoti Tau-Tackling Preterm: a data-linkage methodology to explore the clinical care pathway in preterm deliveries

Background

Significant health inequities exist around maternal and infant health for Māori, the indigenous people of Aotearoa New Zealand – and in particular around a premature (preterm) delivery. Māori babies are more likely to be born preterm (8.1%, compared to an overall rate of 7.4%) and they are more likely to have a preterm death. An essential part of redressing these disparities is to examine the clinical care pathway and outcomes associated with preterm deliveries. This paper describes a protocol utilising national and local health collections to enable such a study.

Design

This is a retrospective cohort study comprising 5 years data pertaining to preterm deliveries from 2010 to 2014. These data are generated from linked national administrative and local health information collections to explore a range of neonatal outcomes and infant mortality in relation to the antenatal care pathway and known risk factors for preterm delivery. This study is being conducted within a Kaupapa Māori paradigm that dismisses victim blaming and seeks to intervene at structural levels to improve the health and wellbeing of Māori whānau (family).

Significance of the study

Our data-linkage methodology optimises the utility of New Zealand health collections to address a significant health issue. Our findings will fill the information gaps around the burden of preterm delivery by quantifying the incidence of preterm delivery and adverse neonatal and infant outcomes in Aotearoa New Zealand. It will explore access to evidenced based care including use of steroids before birth, and appropriate place of delivery. The results from this study will inform maternity care services to improve management of preterm deliveries – both locally and internationally. This in turn will improve the preterm sequela by reducing the long-term health burden and health inequities.

Severe maternal morbidity due to sepsis: The burden and preventability of disease in New Zealand

BACKGROUND

Sepsis is a life-threatening systemic condition that appears to be increasing in the obstetric population. Clinical detection can be difficult and may result in increased morbidity via delays in the continuum of patient care.

AIMS

To describe the burden of severe maternal morbidity (SMM) caused by sepsis in New Zealand and investigate the potential preventability.

METHODS

A multidisciplinary expert review panel was established to review cases of obstetric sepsis admitted to intensive care or high-dependency units over an 18 month span in New Zealand. Cases were then analysed for the characteristics of infection and their preventability.

RESULTS

Fifty cases met the inclusion criteria, most commonly due to uterine, respiratory or kidney infection. Fifty per cent (25) of these cases were deemed potentially preventable, predominantly due to delays in diagnosis and treatment.

CONCLUSIONS

A high index of suspicion, development of early recognition systems and multi-disciplinary training are recommended to decrease preventable cases of maternal sepsis.

Information, support, and follow-up offered to women who experienced severe maternal morbidity

OBJECTIVE

To determine what information, support, and follow-up were offered to women who had experienced severe maternal morbidity (SMM).

METHODS

The present retrospective case review included patients who experienced SMM (admission to intensive care during pregnancy or up to 42 days postpartum) who had previously been reviewed for potential preventability as part of a nationwide New Zealand study performed between January 1 and December 31, 2014. Data were audited to ascertain documented evidence of an event debrief or explanation; referral to social support and/or mental health services; a detailed discharge letter; and a follow-up appointment with a specialist.

RESULTS

Of 257 patients who experienced SMM, 23 (8.9%) were offered all four components of care, 99 (38.5%) an event debrief, 102 (39.7%) a referral to social support and/or mental health services, 148 (57.6%) a detailed discharge letter, and 131 (51.0%) a follow-up appointment.

CONCLUSIONS

Many women who had experienced SMM did not receive explanatory information about their illness, an offer of psychosocial support, or a follow-up appointment prior to discharge from hospital. It is incumbent on clinicians and the maternity care system to improve these aspects of care for all women experiencing a potentially life-changing SMM event to minimize the risk and burden of long-term mental illness.

Views of the obstetric profession on non-invasive prenatal testing in Aotearoa New Zealand: A national survey

BACKGROUND

Non-invasive prenatal testing (NIPT) has been available in Aotearoa New Zealand (NZ) for approximately four years. It is likely to be introduced into the publicly funded prenatal screening service.

AIM

To explore obstetrician use and views of NIPT, with consideration to its implementation into screening services for Down syndrome and other conditions.

METHODS

An anonymous online survey combining Likert scales and free text was designed to assess current practice, knowledge, ethical considerations, counselling and views toward public funding of NIPT. The survey was distributed through the New Zealand members of the Royal Australian and New Zealand College of Obstetricians and Gynaecologists (n = 418) and responses collected over a two-month period in 2016.

RESULTS

There were 134/418 (32.1%) respondents. Current knowledge influenced decisions to offer NIPT (70.3%, 85/121). Confidence in offering NIPT was: 'not at all' (0.8%, 1/128); 'a little' (7.03%, 9/128), 'somewhat' (16.4%, 21/128), 'quite' (40.6%, 52/128) and 'very' (35.2%, 45/128). A total of 83.5% (101/121) stated NIPT should be publicly funded and NIPT capability developed within NZ (89.1%, 106/119). More information and support on the provision of NIPT was called for.

CONCLUSION

There was strong support for public funding of NIPT, and for NIPT capability to be developed in NZ. The call for more training, education and support needs to be actioned in order to facilitate the introduction of NIPT into screening services.

Pounamu: E Hine: access to contraception for indigenous Mãori teenage mothers

ABSTRACT INTRODUCTION Timely and equitable access to contraception enables teenage mothers to make informed choices about their sexual and reproductive health. This study aimed to identify barriers and facilitators to contraception for Māori teenagers who become mothers. METHODS ‘E Hine’ is a longitudinal qualitative Kaupapa Māori (by Māori for Māori) study involving Māori women (aged 14–19 years), following them through pregnancy (n = 44) and the birth of their babies until their babies’ first birthdays (n = 41). This analysis focusses on contraception access pre-and post-pregnancy. FINDINGS Pre-pregnancy most participants accessed contraception or advice. Contraception use was compromised by a lack of information, negative side effects, and limited follow up. All reported their subsequent pregnancies as unplanned. Participants gave considerable thought to post-pregnancy contraception. Despite this many experienced clinical and service delays, financial barriers, and negative contraceptive side effects. There was little focus on contraception initiation and a lack of integrated care between midwives and other primary care services, leaving many participants without timely effective contraception. The system worked well when there was a contraception plan that included navigation, free access, and provision of contraception. CONCLUSION The majority of participants actively sought contraception pre- and post-conception. Despite a publicly funded system, a lack of health sector integration resulted in multiple missed opportunities to meet the needs of these teenagers for effective contraception. Health service funding formulas should define the goal as initiation of contraception rather than advice and provide funding to improve timely access to long acting reversible contraception.

Uterine cancer: exploring access to services in the public health system

BACKGROUND

Māori are the indigenous peoples of New Zealand and experience higher rates of uterine cancer and poorer survival rates. Postmenopausal bleeding (PMB) is the most common presenting symptom for uterine cancer. Prompt investigation is essential with 28 days being viewed as an appropriate time from first medical contact (FMC) to first specialist appointment (FSA).

AIMS

To compare access to services for the investigation of PMB between Māori and non-Māori women.

MATERIALS AND METHODS

The time interval between FMC to FSA was obtained from medical records for women presenting to gynaecology clinics for PMB. Dates of first bleeding symptoms, knowledge and access issues were collected in a nurse-administered questionnaire.

RESULTS

A total of 154 women (n = 27 Māori and 127 non-Māori) participated in the study. 23% of women had their FSA from FMC within 28 days and 67% waited more than six weeks. The 75th percentile was approximately two weeks longer for Māori women. 25% (n = 37) of women were not aware that they needed to see a doctor about PMB, and this was significantly more common for Māori women (44%; 95% CI 25-65) than non-Māori women (20%; 95% CI 13-28; P = 0.011).

CONCLUSIONS

The majority of women were not seen for FSA within 28 days of their FMC. Māori women were more likely to experience lengthy delays and to report that they did not know they should see a doctor about PMB. Further investigation into reasons for delays and initiatives to improve access to services and health information appears warranted.

Preventability of severe acute maternal morbidity

OBJECTIVE

We sought to assess potential preventability of severe acute maternal morbidity (SAMM) cases admitted to intensive-care units (ICUs) or high-dependency units (HDUs).

STUDY DESIGN

Inclusion criteria were admissions to ICUs or HDUs of women who were pregnant or within 42 days of delivery in 4 District Health Board areas (accounting for a third of annual births in New Zealand) during a 17-month period. Cases were reviewed by external multidisciplinary panels using a validated model for assessing preventability.

RESULTS

In all, 98 SAMM cases were assessed; 38 (38.8%) cases were deemed potentially preventable, 36 (36.7%) not preventable but improvement in care was needed, and 24 (24.5%) not preventable. The most frequent preventable factors were clinician related: delay or failure in diagnosis or recognition of high-risk status (51%); and delay or inappropriate treatment (70%). The most common causes of preventable severe morbidity were blood loss and septicemia.

CONCLUSION

The majority of SAMM cases were potentially preventable or required improvement in care. Themes around substandard care related to delay in diagnosis and treatment for postpartum hemorrhage and septicemia. These findings can inform clinical educational programs and policies to improve maternal outcomes. This study has now been expanded to a national New Zealand audit of all SAMM cases admitted to an ICU/HDU.

Breast cancer and breast screening: perceptions of Chinese migrant women living in New Zealand

INTRODUCTION

Migrant Chinese constitute a significant and increasing proportion of New Zealand women. They have lower rates of participation in breast cancer screening than other New Zealanders, but reasons for this are unknown. The aim of this study was to investigate factors affecting Chinese women's understanding of, and access to, breast health services, to better understand reasons for low participation in screening and their experiences of breast cancer clinic care.

METHODS

The participants were 26 Chinese migrant women-19 recruited in the community and seven recruited from 17 eligible women attending a breast clinic between 2008 and 2010 in Wellington, New Zealand. The design was that of a qualitative study, using semi-structured interviews and thematic content analysis.

FINDINGS

There were low levels of awareness about the national breast screening programme and limited engagement with preventive primary care services. Concerns about privacy and a range of communication difficulties were identified that related to oral language, lack of written information in Chinese, and limited understanding about Chinese perceptions of ill health and traditional Chinese medicine by New Zealand health professionals.

CONCLUSION

Addressing communication barriers for Chinese migrant women has the potential to raise awareness about breast cancer and breast health, and to increase successful participation in breast cancer screening. Greater efforts are needed to ensure this group has an understanding of, and is engaged with a primary care provider. Such efforts are key to improving health for this growing sector of the New Zealand population.

Poor compliance with standard precautions against infections during minor gynaecological procedures

BACKGROUND

Splash injuries occurring during minor surgical procedures are associated with a significant infective risk to the operator. It is a common misconception that minor operations carry low risks.

AIM

To determine the prevalence of the practice of Standard Precautions by medical staff in the obstetric and gynaecology (O & G) units of two hospitals in New Zealand, and to assess self-observed splash injury rates.

METHOD

A cross-sectional survey of all doctors working in the O & G units of two public hospitals servicing a population of 435 000. A self-administered questionnaire was provided to 43 doctors with questions related to the use of Standard Precautions, perceived likelihood of infection from a splash and splash injuries sustained during procedures.

RESULTS

The response rate was 76.6% (n = 33/43). Of the respondents, only 30.3% (n = 10) used Standard Precautions during minor procedures. Sixty-four per cent (n = 21) routinely used goggles/visor for eye protection. Forty-five per cent (n = 15) thought they were likely to get an infection from a splash, and 55% (n = 18) of clinicians had experienced a splash injury. Of the minor procedures during which splash injuries had occurred, repair of episiotomy 45.8% (n = 11) was the commonest.

CONCLUSIONS

This survey shows poor compliance with guidelines for Standard Precautions to protect from infection despite self-reported rates of splash injury being high at 55%. Effective interventions are needed to increase compliance and prevent infection.

HPV/cervical cancer vaccination: parental preferences on age, place and information needs

INTRODUCTION: A vaccine against cervical cancer is available in New Zealand through school and primary care for girls aged 12–18 years. Factors that might increase or hinder widespread uptake by the target population need to be identified. Aim: To describe parents’ preferences on where their daughter(s) receive the human papillomavirus (HPV) vaccine, at what age, and their information needs. METHODS: 3123 questionnaires were distributed to parents recruited from 14 schools in 2008, prior to the start of the school-based vaccination programme. Outcome measures were: preferred age and place of vaccination, and information needs of parents and their daughters. Tests for significance were performed to determine whether parental preferences differed by ethnic group (Maori, Pacific, New Zealand European and ‘Other’). RESULTS: A 25% response rate was achieved (769/3123). Receipt of the HPV vaccine in a clinic setting was preferred by 40% of parents; 25% preferred vaccination at school. Fifty percent preferred vaccination to occur at age 13 or older; 28% thought ages 10, 11 or 12 appropriate. One in three parents wanted more information and 65% said they would seek information from their family doctor before deciding on the vaccine for their daughter(s). DISCUSSION: We suggest that a programme delivered jointly in primary care and school settings, that is appropriately resourced for follow-up and information-sharing, would increase vaccine coverage. The rationale for vaccination at age 12 needs to be made clear to parents and evidence-based information needs to be delivered appropriately to parents and girls.

Increasing the uptake of opportunistic chlamydia screening: a pilot study in general practice

INTRODUCTION: Genitourinary Chlamydia trachomatis infection is common and associated with considerable personal and public health cost. Effective detection strategies are needed. Aim: To assess feasibility of an opportunistic incentivised chlamydia screening programme in general practice over six months. METHODS: This study was designed as a pilot for a randomised controlled trial in primary care. Three general practices were randomly allocated to intervention (two practices) and control groups. The intervention involved practice education, self-sample collection and practice incentives (funding and feedback) for a three-month ‘active’ intervention period. Feedback and education was discontinued during the second three-month period. Practice-specific nurse- or doctor-led strategies were developed for identifying, testing, treating and recalling male and female patients aged 16–24 years. The main outcome measure was the difference between the practices’ chlamydia screening rates over the six months following introduction of the intervention, controlling for baseline rates from the previous year. RESULTS: Chlamydia testing rates during the year prior to the intervention ranged from 2.9% to 7.0% of practice attendances by 16–24-year-olds. The intervention practices had higher rates of screening compared with the control practice (p<0.001) at three months, but both practices reverted to pre-intervention rates by six months. The nurse-led screening strategy was more effective (35% declining to 5.5% over six months) than the doctor-led strategy (15% declining to 1.6% over six months) (p=0.04). DISCUSSION: Incentivised opportunistic chlamydia screening of 16–24-year-old patients attending their general practitioner with a programme involving practice education, feedback and self-sample collection can increase screening rates.

Effectiveness of a falls-and-fracture nurse coordinator to reduce falls: a randomized, controlled trial of at-risk older adults

OBJECTIVES

To assess the effectiveness of a community-based falls-and-fracture nurse coordinator and multifactorial intervention in reducing falls in older people.

DESIGN

Randomized, controlled trial.

SETTING

Screening for previous falls in family practice followed by community-based intervention.

PARTICIPANTS

Three hundred twelve community-living people aged 75 and older who had fallen in the previous year.

INTERVENTION

Home-based nurse assessment of falls-and-fracture risk factors and home hazards, referral to appropriate community interventions, and strength and balance exercise program. Control group received usual care and social visits.

MEASUREMENTS

Primary outcome was rate of falls over 12 months. Secondary outcomes were muscle strength and balance, falls efficacy, activities of daily living, self-reported physical activity level, and quality of life (Medical Outcomes Study 36-item Short Form Questionnaire).

RESULTS

Of the 3,434 older adults screened for falls, 312 (9%) from 19 family practices were enrolled and randomized. The average age was 81+/-5, and 69% (215/312) were women. The incidence rate ratio for falls for the intervention group compared with the control group was 0.96 (95% confidence interval=0.70-1.34). There were no significant differences in secondary outcomes between the two groups.

CONCLUSION

This nurse-led intervention was not effective in reducing falls in older people who had fallen previously. Implementation and adherence to the fall-prevention measures was dependent on referral to other health professionals working in their usual clinical practice. This may have limited the effectiveness of the interventions.

Main morbidities recorded in the women's international study of long duration oestrogen after menopause (WISDOM): a randomised controlled trial of hormone replacement therapy in postmenopausal women

OBJECTIVE

To assess the long term risks and benefits of hormone replacement therapy (combined hormone therapy versus placebo, and oestrogen alone versus combined hormone therapy).

DESIGN

Multicentre, randomised, placebo controlled, double blind trial.

SETTING

General practices in UK (384), Australia (91), and New Zealand (24).

PARTICIPANTS

Postmenopausal women aged 50-69 years at randomisation. At early closure of the trial, 56,583 had been screened, 8980 entered run-in, and 5692 (26% of target of 22,300) started treatment.

INTERVENTIONS

Oestrogen only therapy (conjugated equine oestrogens 0.625 mg orally daily) or combined hormone therapy (conjugated equine oestrogens plus medroxyprogesterone acetate 2.5/5.0 mg orally daily). Ten years of treatment planned.

PRIMARY OUTCOMES

major cardiovascular disease, osteoporotic fractures, and breast cancer.

SECONDARY OUTCOMES

other cancers, death from all causes, venous thromboembolism, cerebrovascular disease, dementia, and quality of life.

RESULTS

The trial was prematurely closed during recruitment, after a median follow-up of 11.9 months (interquartile range 7.1-19.6, total 6498 women years) in those enrolled, after the publication of early results from the women's health initiative study. The mean age of randomised women was 62.8 (SD 4.8) years. When combined hormone therapy (n=2196) was compared with placebo (n=2189), there was a significant increase in the number of major cardiovascular events (7 v 0, P=0.016) and venous thromboembolisms (22 v 3, hazard ratio 7.36 (95% CI 2.20 to 24.60)). There were no statistically significant differences in numbers of breast or other cancers (22 v 25, hazard ratio 0.88 (0.49 to 1.56)), cerebrovascular events (14 v 19, 0.73 (0.37 to 1.46)), fractures (40 v 58, 0.69 (0.46 to 1.03)), and overall deaths (8 v 5, 1.60 (0.52 to 4.89)). Comparison of combined hormone therapy (n=815) versus oestrogen therapy (n=826) outcomes revealed no significant differences.

CONCLUSIONS

Hormone replacement therapy increases cardiovascular and thromboembolic risk when started many years after the menopause. The results are consistent with the findings of the women's health initiative study and secondary prevention studies. Research is needed to assess the long term risks and benefits of starting hormone replacement therapy near the menopause, when the effect may be different.

Falls Assessment Clinical Trial (FACT): design, interventions, recruitment strategies and participant characteristics

BACKGROUND

Guidelines recommend multifactorial intervention programmes to prevent falls in older adults but there are few randomised controlled trials in a real life health care setting. We describe the rationale, intervention, study design, recruitment strategies and baseline characteristics of participants in a randomised controlled trial of a multifactorial falls prevention programme in primary health care.

METHODS

Participants are patients from 19 primary care practices in Hutt Valley, New Zealand aged 75 years and over who have fallen in the past year and live independently. Two recruitment strategies were used - waiting room screening and practice mail-out. Intervention participants receive a community based nurse assessment of falls and fracture risk factors, home hazards, referral to appropriate community interventions, and strength and balance exercise programme. Control participants receive usual care and social visits. Outcome measures include number of falls and injuries over 12 months, balance, strength, falls efficacy, activities of daily living, quality of life, and physical activity levels.

RESULTS

312 participants were recruited (69% women). Of those who had fallen, 58% of people screened in the practice waiting rooms and 40% when screened by practice letter were willing to participate. Characteristics of participants recruited using the two methods are similar (p > 0.05). Mean age of all participants was 81 years (SD 5). On average participants have 7 medical conditions, take 5.5 medications (29% on psychotropics) with a median of 2 falls (interquartile range 1, 3) in the previous year.

CONCLUSION

The two recruitment strategies and the community based intervention delivery were feasible and successful, identifying a high risk group with multiple falls. Recruitment in the waiting room gave higher response rates but was less efficient than practice mail-out. Testing the effectiveness of an evidence based intervention in a 'real life' setting is important.
